The grinding process of PCD cutters has become one of the obstacles in its popularization and application. In order to break the bottleneck of this process, domestic and foreign scholars have conducted a lot of research and development work.

The main grinding process of PCD cutting tools is electric discharge sharpening, diamond grinding wheel mechanical sharpening, electrolytic sharpening, etc. Among them, the electric discharge sharpening and diamond grinding wheel mechanical sharpening are relatively mature in technology, but the electric discharge sharpening will affect the surface of the hard alloy. Forming a micro crack with a depth of about 0.05 mm, so the diamond grinding wheel mechanical sharpening is currently the most widely used PCD tool sharpening method.

According to different bonding agents, diamond grinding wheel is divided into: resin bond diamond grinding wheel, metal bond diamond grinding wheel, ceramic bond diamond grinding wheel. The resin binder is soft, easily deformed during grinding, and can not effectively grind PCD cutters; the metal binder has poor self-sharpness and low grinding efficiency due to its strong binding ability to the abrasive particles, and the metal binder grinding wheel It will cause the most serious damage to the edge of the PCBN tool; for comprehensive grinding efficiency, durability of the grinding tool and machining quality of the workpiece surface, the ceramic diamond grinding wheel is suitable for processing PCD cutting tools.

Ceramic diamond grinding wheel as a highly efficient rotating part, its unbalanced value directly affects the vibration of the grinding wheel working and the working life of the machine tool and the grinding precision of the object being processed. As the requirements for the surface quality of the parts to be machined are increasing, the rotational speed of the grinding wheel is further increased, and the requirements for the balance accuracy are also increasing. It is particularly important to select a reasonable balance method.

Because the structure of the grinding wheel is composed of a large number of unevenly distributed particles, mechanical machining errors, and assembly errors, the main inertia axis passing through the center of gravity of the diamond grinding wheel does not coincide with the rotation center, and thus an imbalance occurs when the diamond grinding wheel rotates at a high speed. Centrifugal force. Centrifugal force is one of the main causes of bearing wear and mechanical vibration. It seriously affects the machining precision and the service life of the machine tool. It also reduces the spindle life of the grinder, the life of the grinding wheel, the number of grinding wheel corrections, and the consumption of dressing diamonds. Therefore, in the manufacture of diamond grinding wheel, dynamic balance must be corrected.

Decathlon® uses the latest research results as a hard-support dynamic balancing machine. Its core balancing instrument is imported from Japan, and the elastic system uses H-type support, which is highly resilient and stable. The transmission method adopts a belt drive and has good stability. The test signal uses an advanced photoelectric signal as a phase reference signal. The electromechanical transducer adopts a lever type mechanical amplification mechanism and a magnetoelectric speed sensor, and the output is large and the performance is stable and reliable.

Each wheel of DeKatte® company has a professional dynamic balance tester to perform balancing tests before leaving the factory. Make sure that the balance of each wheel is stable to a minimum of the residual imbalance emar <0.3g.mm/kg. Dekate's grinding wheels can only be shipped after the balancing test is done. Customers can use it safely.

The use of a wheel that performs a balancing test can meet the surface finish and precision of a customer's machined workpiece to the greatest extent possible, reduce the load and wear of grinder bearings, high-speed rotary spindles, etc., and reduce grinding vibration and workpiece burn damage. Significantly reduce production costs such as renewal or maintenance.

Choosing the grinding wheel made by Decathlon® Company and choosing the balancing wheel will create the most competitive and superior processing quality and lowest processing cost for customers. De Carter® grinding wheels are ideal for grinding PCD tools.
